The answer is 30%.... because 50/65 is .3
Answer:
D) 32
Step-by-step explanation:
sin∠30=16/x first calculate sin∠30
1/2=16/x next cross multiply
x=32
Have a good day :)
Step-by-step explanation:
Since the focus lies on the x axis, and the diretcrtirx is a vertical line, we have a sideways parabola so we have the equation
where h,k is the vertex and
p is the distance from the vertex to the focus or the distance fromcthe vertex to the directrix.
Since the focus is 1.5, and the directrix is -1.5 the vertex is (0,0) so we have
We know p is 1.5 so we have
Answer:
V = 205 in^3 to the nearest whole number
Step-by-step explanation:
V = 4/3 π r^3
Plugging in the given information:
V = 4/3 * 3.14 * 7^2
V = 205.147.
The quantity that has been decreased,
2.98-2.32=0.66
That is,
0.66/2.98*100=22%
